Plasmon / interband transitions coupling in the UV from large scale nanostructured Ni films

Abstract

We report on the synthesis of Ni nanoparticles via thin film thermal annealing. The as prepared particles exhibit a tunable average diameter ranging from 13 nm to 44 nm depending on the initial deposited film thickness and are covered with a stable NiO x shell. This technique is suitable for large scale fabrication of Ni nanoparticles onto substrates. The study of the magnetic and optical properties of these nanostructures revealed a ferromagnetic behaviour at room temperature and a localized surface plasmon resonance in the UV-range, promoting Ni nanoparticles as a suitable material for UV-plasmonic applications. The coupling between plasmon and interband transitions have also been studied.
